We look at the division of 15390579 by 227 
The aim is to understand the frequency of 227 in 15390579.

Advancing to step 1:
The number 227 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 227

Advancing to step 2:
The number 227 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 227

Advancing to step 3:
153 divided by 227 is 0 with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 153 leaves us with 153.
Grab the next digit (9) from the dividend, add it to 153, then carry on: 1539 / 227

Let's proceed to step 4:
227 can be fit into 1539 6 times, resulting in a remainder of 177.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 1362 from 1539 to get 177.
Bring next digit (0) of the dividend behind the 177 and repeat the process: 1770 / 227

Advancing to step 5:
When dividing 1770 by 227, we get 7 with a remainder of 181.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we subtract 1589 from 1770, we get 181.
Take the next digit (5) from the dividend and append it to 181, then repeat: 1815 / 227

On to step 6:
If we divide 1815 by 227, we get 7 and a remainder of 226.
Record the quotient 7 as the next digit in the result. 
Result so far: 677.0
Subtracting 1589 from 1815 leaves us with 226.
Include the next digit (7) from the dividend after 226, then repeat: 2267 / 227

Let's proceed to step 7:
227 goes into 2267 9 times with a remainder of 224.
The next digit of our result is 9. 
Result so far: 6779.0
Subtract 2043 from 2267 to get 224.
Include the next digit (9) from the dividend after 224, then repeat: 2249 / 227

Moving on to step 8:
When dividing 2249 by 227, we get 9 with a remainder of 206.
The next digit of our result is 9. 
Result so far: 67799.0
If we take 2043 away from 2249, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 9:
The number 227 fits into 2060 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 67799.9
Subtract 2043 from 2060 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
170 divided by 227 is 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 67799.9
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
The number 227 fits into 1700 7 times, leaving a remainder of 111.
Write down 7 as next digit of the result. 
Result so far: 67799.907
Subtract 1589 from 1700 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 12:
227 can be fit into 1110 4 times, resulting in a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 67799.9074
Subtract 908 from 1110 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 13:
The number 227 fits into 2020 8 times, leaving a remainder of 204.
Use 8 as the next digit of our solution. 
Result so far: 67799.90748
Subtracting 1816 from 2020 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 14:
The number 227 fits into 2040 8 times, leaving a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 67799.907488
If we take 1816 away from 2040, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

In conclusion, the division gives 67799.907488 with a balance of 2.24e-05.
